5 Claims.

This invention relates to a detachable vehicle wheel, the general object of the invention being to provide means whereby the wheel can be easily and quickly removed from the brake drum and just as easily attached to the drum, by manual movement axially of a ring-shaped member, this movement of said ring-shaped member actuating the holding means which hold the wheel to the drum.

l'his invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in-the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which-- Figure 1 is an elevational view with parts broken away showing a wheel assembly provided with the invention.

Figure 2 is a' view approximately on the line 2-2 of Figure 1 with the wheel fastened to the drum.

Figure 3 is a similar view but with the wheel removed from the drum.

Figure 4 is a fragmentary sectional view through the drumand showing one of the studs. Figure 5 is a section on line 55 of Figure 3. Figure 6 is a view of one of the arm members having the keyhole shaped opening therein receiving'a stud.

In these views the letter A indicates a brake drum of a wheel and the letter W indicates a portion of the wheel. These parts are of conventional or any desired construction and in carrying out the invention I provide a plurality of studs l which are riveted to the drum as shown and each stud has a head 2 at its outer end and each head is provided with a pair of slots 3 therein, these slots being arranged opposite each other and are beveled, as shown at 3', with the bevel tapering toward the hub. The wheel is provided with an annular part 4 which is formed with a plurality of holes 5 for receiving the heads of the studs. The annular part is formed with an axially extending flange 6 which has slots 1 therein, these slots 1 being arranged adjacent the holes 5, as shown.

A plurality of arms 8, of flat construction, are slidably arranged on the flange 4 and each arm is provided with a head 9 having a substantially keyhole shaped opening l0 therein for fitting over a stud head 2 and a reduced part II extends from each head 9 and slidingly engages a slot 1. The enlarged part of the opening I0 is of greater area than the head of the stud so that it can pass over the head but the narrow part III of the opening will engage the slots 3 in the head, when the arm 8 is moved inwardly. When the arm is moved outwardly the shoulders ll formed by the reduced part II, will engage the flange 6 which limits outward movement of the arm and holds the enlarged part of the openingdifl in position to receive the head 2 of a s u Y A pair of outwardly diverging springs l2 have their inner ends connected with opposite sides of 16 the intermediate part of each arm 8. .The other ends of the springs are connected with the annular part 4 and these springs tend to move the arms outwardly with the shoulders ll engaging the flange 6 and the enlarged parts of the openings in position to receive the studs.

The inner end of each arm 8 is bent outwardly first at right angles to form a shoulder 8' and then at an acute angle, as shown at l3, and this bent part is formed with a longitudinally extending elongated slot l4 through which passes one end of a pin IS, the other end of which has an eye l6 therein through which passes a ring member I! which is located adjacent the outer end of the hub of the wheel when the wheel is in place. 'A spring i8 is located on each pin and has one end bearing against a washer l9 which also bears againstv the bent part of the arm and the pin is held in the slot I4 of the bent part by a cotter pin 20.

The ring member I! acts as a handle for manipulating the arms to locking and unlocking position. When the ring member I! is moved outwardly to the position shown in Figure 3 the pins l5 will be caused to move the arms 8 outwardly to place the large parts of the openings over the heads of the studs so that the wheel can be pulled from the studs or if the wheel is already oil the drum then in this position of the parts the wheel can be readily placed against the drum with the heads of the studs passing through the largest parts of the openings it. Then the ring member I! is forced inwardly and as this is done the pins l5 are pressed inwardly to the position shown in Figure 2' and in this position of the parts the springs 18 will force the washers l9 against the shoulders 8' at the inner ends of the arms 8 so that the pressure of the springs moves the arms inwardly and thus causes the small parts ill of the openings ill to 5 engage the slots 3 in the heads of the studs and thus the wheel will be locked to the drum. Due to the beveling 3' of the slots 3 01 the stud heads, as parts of the arms enter the slots, the wheel parts will be caused to press firmly against the drum part to tightly hold the wheel against the drum.

In order to increase the wedging action between the heads 2 of the studs and the outer ends of the arms 8 those portions of the heads 9 of the arms 8 adjacent the slots III are beveled, as at I0" in Figure 6. Thus the wedge or beveled face of the walls of the slots l0 together with the bevels of the. slots 3 in the studs will cause the wheel to be moved tightly against the drum as the arms move inwardly under the action of the springs l8 and thus the wheel is firmly locked to the drum at a plurality of points so that there is absolutely no danger of the wheel wobbling and while the drawings show the studs as riveted to the drum it is to be understood that such studs will be formed with the drum when the drums are manufacturedsin accordance with the invention.

Thus the wheel is firmly connected with the drum and then when it is desired to release the wheel from the drum it is simply necessary to pull the ring member l1 outwardly to the position shown in Figure 3 to move the arms 8 outwardly so that the enlarged parts of the openings ID will register with the heads of the studs so that the arms can be passed over the heads as the wheel is being pulled from the drum.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claims. I

What I claim is: 1. Means for connecting a wheel part to a carrying part comprising headed studs on the car- Y rying part, each head having oppositely arranged slots therein, arms slidably carried by the wheel part and having substantially keyhole shaped openings therein, the large parts of which are of greater area than the area of the heads of the studs, with the small parts of the openings having their side walls engaging the slots, when the arms are moved inwardly, a handle member, and means, including spring means, for connecting the handle member with the inner ends of the arms for moving the arms outwardly, when the handle member is moved outwardly, to release the arms from the studs and when the handle member is moved inwardly the arms are moved inwardly to cause the small parts of the openings to engage the slots of the heads of the studs.

2. Means for connecting a wheel part to a drum part comprising headed studs carried by the drum part, each head having a pair of diametrically arranged slots therein, a plurality of arms slidably arranged on parts of the wheel part and each arm having a substantially keyhole shaped opening therein, the large part of which is of greater area than the head of a stud and the small part of which has its walls engaging the slots in said head when an arm is moved inwardly, each arm having an outwardly turned part provided with a slot, a ring member, pins having ring-shaped heads through which the ring member passes, said pins having their free ends passing through the slots of the arms, means for holding said ends in said slots, springs surrounding the pins and pressing against the turned ends of the arms, when the ring member is moved inwardly to move the arms inwardly, the arms being moved outwardly by the pins when the ring member is moved outwardly.
